The Mail Onlinereports the Swiss authorities have "formally accused" the man, known as Marc, with the "intentional murder" of his British girlfriend.

"A 29-year-old German citizen was arrested on April 9," a spokesperson from the Cantonal police told the publication. "Today he has been formally accused of intentional murder with the possibility of the lesser charge of involuntary homicide after the investigation, which is ongoing.

"The autopsy has been carried out but the conclusion has not yet reached the Public Ministry."

However, Marc's ex-partner and the mother of his two children, who cannot be identified for legal reasons, has insisted he is not capable of murder, the outlet reports.

Marc had been staying at a hotel in Switzerland with Reed, who is originally from Yorkshire in the UK, earlier this week.

The couple were heard arguing in the early hours on Tuesday morning, with other guests reportedly complaining about the noise at around 3am.
